REPORT ON THE ECHINOIDEA, 203 



junction with the peripetalous fascicle. The arrangement of the spines is somewhat 

 peculiar ; in addition to the usually larger spines found in Schizasteroids on the edges 

 of the petals and of the odd ambulacral groove, tufts and patches of considerable 

 size of similar larger spines are found as in other genera, not only on each side of 

 the anal system and at the extremity of the actinal beak (PL XXXVI. fig. 9), but also 

 in the ambital region of the lateral anterior iuterambulacral areas (PL XXXVI. 

 figs. 8, 10), and in the anterior half of the lateral posterior iuterambulacral areas from 

 the posterior edge of the anterior lateral petals to the edge of the test (PL XXXVI. 

 fig. 10). The rest of the abactinal surface of the test is covered with short spines of 

 nearly uniform length and size. On the actinal side the spines are longer, coarser, and 

 more distant (PL XXXVI. fig. 9), corresponding to the tuberculation of that region (PL 

 XXXVI. fig. 13). 



Tlie pedicellarije of Schizaster japonicus (PL XLIII. fig. 26 ; PL XLV. figs. 7-10), 

 are stout-headed and stout-stemmed, few in number, scattered irregularly on the test, 

 and stand out prominently from the test owing to their dark violet colour.

"^Schizaster moseleyi, n. sp. (PL XXXVI. figs. 14-16). 



The general facies of this species recalls Schizaster frag iUs and Schizaster 2-)hiUx)pii ; 

 it has like these species a flattened test, lateral ambulacra only slightly sunken, a 

 broad odd anterior ambulacrum with angular edges on the abactinal side and three 

 genital openings. It has, however, like Schizaster gibherulus and Schizaster ventricosus 

 no latero-anal fasciole, some specimens showing a -delicate and most indistinct anal 

 fasciole. The position of the apex is intermediate between that which it occupies in such 

 species as Schizaster fragUis and in Schizaster canaliferus. The colouring is like that of 

 Schizaster pihilipjni (when in alcohol), of an olive green. 



In young specimens measuring about 1 5 mm. the outline is much the same as in the 

 adult (55 mm.); the posterior extremity of the peripetalous fasciole is more pointed 

 owing to the small size of the posterior pair of lateral ambulacra, which are reduced to 

 two or three pairs of pores ; with increasing size this part of the fasciole broadens in pro- 

 portion to the increase in width of the posterior lateral ambulacra. 



Station 311. January 11, 1876. Lat. 52° 50' S., long. 73° 53' W. ; 245 fathoms;
